Occupational Health & Safety Management

ISO 4801:2001 specifies the occupational hygiene that is required by organisations and is applicable to all activities in all sectors. The standard takes into account different levels of risk exposure based on chemical, physical or biological hazards and provides a number of provisions for managing risk.

The first edition of ISO 4801 was published in 1982. Following a four-year revision project, the second edition of ISO 4801 was published in 2003. During this process it became clear that there were several ambiguities and misinterpretations within the standard. Furthermore, significant changes had occurred since 1982 which required consideration e.g. new legislation, guidelines and standards had been developed for certain aspects of occupational hygiene. Therefore, the revision project was launched with the objective of developing a new work based on an improved structure and enhanced clarity in order to address these issues.

Recent OHS Certification Updates

ISO 4801:2001 is significant in that it represents an evolution from its predecessors. Key changes include better alignment of terminology and processes, enhanced guidance for ergonomics and task analysis and significant changes to the way risk management is addressed. The standard has been updated in light of new legislation e.g. the introduction of the General Data Protection Regulation (GDPR) and an increased focus on work-related stress and psychosocial risks. Furthermore, ISO 4801:2016 provides more detailed guidance on responsibility, roles and lines of communication and the role of a comprehensive occupational hygiene management system within an organisation.

ISO 4801:2001 is aimed at helping organisations develop and maintain an occupational hygiene management system that is focused on improving employees’ health and safety. The standard takes into account different levels of risk exposure based on chemical, physical or biological hazards and provides a number of provisions for managing risk.

Who Needs ISO 4801?

ISO 4801 is applicable to all activities in all sectors. All employees are provided with a safe and healthy work environment which ensures the well-being of both individuals and organisations as a whole in line with the relevant legislation for each country.

The standard provides guidance on organisational aspects that impact on occupational hygiene such as decision-making, compliance, policy implementation and review. ISO 4801 also provides guidance on identifying the hazards and risks as well as determining the control measures necessary.
